Where You Live

Air Quality Index (AQI)
The AQI tells you how clean the air is and whether it will affect your health. Here you can find current conditions, forecasts of next-day air quality and web cams that allow you to see current conditions in selected locations.

Ground-level Ozone Designations
Determine whether the area where you live meets ozone-related health standards (is in attainment or nonattainment). You can also follow the process that led to your local ozone attainment/nonattainment determination.

Particulate Matter (2.5) Designations
Determine what recommendations are being made as to whether the area where you live meets particulate pollution-related health standards (will be in attainment or nonattainment). You can also follow the process leading to your local PM 2.5 attainment/nonattainment determination. (This determination will be made by December 31, 2004.)
